Expert Solution
Step 1
Scenario:
A man is hanging from the top and bounded by a chain such that man is rotating on the chain.
Let's find why the man said "I'm not even moving, it's doing on it's own" at the end.
Step 2
By conservation :
We know,
Total of system is conserved if net torque is zero.
Therefore, In this scenario, a man is rotating about its axis and rotating across the chain and thus no external torque is experienced by man. Consequently, chain is rotating in its own to conserve the of the system.
Mathematically,
here,
Thus, option(d) is correct.
